A Timeline Rubric for Grading Timeline Projects

A rubric tells students before they start what a good timeline looks like, and it makes grading thirty of them faster and fairer. This article gives a sample timeline rubric you can copy and adapt, then explains how to check each criterion when students build their timelines in Preceden.

What to grade

Most timeline assignments come down to six things:

  • Accuracy. Are the dates right, and do they match the sources?
  • Events. Are there enough events, and do they matter to the topic?
  • Order and spacing. Are the events in chronological order, and is the distance between them drawn to scale?
  • Descriptions. Does each event say what happened and why it matters, not just name it?
  • Sources. Can you tell where each date came from?
  • Layout. Is the timeline easy to read, with a title, clear labels and related events grouped together?

Spelling and grammar can be a seventh row, or folded into Descriptions if you would rather keep the rubric short.

A sample timeline rubric

Each criterion is scored from 1 to 4, for a total out of 24.

Criterion 4 3 2 1
Accuracy Every date is correct One or two dates are wrong Several dates are wrong Most dates are wrong or missing
Events The required number of events, all of them significant The required number, with one or two minor ones A few events short, or several off topic Far fewer events than required
Order and spacing All in order, spaced to scale All in order, spacing slightly off One or two events out of order Events are not in chronological order
Descriptions Each event explains what happened and why it matters Most events explain what happened Descriptions are mostly just names Few or no descriptions
Sources A source for every event Sources for most events A source list, not tied to events No sources
Layout Titled, clearly labeled, related events grouped Titled and readable Hard to read in places Cluttered or unlabeled

Adapting it

For younger students, drop the Sources row and score Order and spacing on order alone. For older ones, raise the bar on Descriptions: a 4 can require the student to connect each event to the one before it, which is where most of the thinking in a timeline project happens.

Set the required number of events before you hand the rubric out, and put it in the Events row. Eight to ten works for most single-period projects. A free Preceden account holds up to 10 events on each timeline, so a requirement of 10 or fewer means no student has to pay to complete the assignment.

If students are allowed to start from an AI-generated draft, say so in the Accuracy row. Timeline Maker AI on Preceden's homepage can draft a timeline on a well-known subject, but drafts get dates wrong and sometimes invent events. Hallucinated Events explains what to look for, and a student who has checked every date against a source has earned the 4.

Grading a Preceden timeline

A Preceden timeline already holds most of what the rubric asks for, so grading is mostly a matter of knowing where to look.

  • Accuracy and order. Preceden places every event by its date, so events cannot be out of order and the spacing is always to scale. That makes Order and spacing an easy 4 for a timeline built here, and leaves your attention for Accuracy.
  • Uncertain dates. Students can check Approx. next to a date in the event dialog when a date is disputed or estimated. Those dates are shown with a leading Approx. or ~, so you can tell a careful estimate from a mistake.
  • Descriptions and sources. Each event has a Notes field that accepts Markdown, including links. Ask students to put the description and the source for each event there. The event list below the timeline shows every event's dates and notes in one place, which is the easiest view to grade from.
  • Layout. Look for related events on their own layers, each with its own color, and a few turning points marked as milestones, which Preceden draws as a vertical line across the whole timeline.

Students can hand the timeline in by sharing a link or by downloading a PDF from Share > PDF. The PDF dialog has Event List checked the first time it opens, so the notes and sources print on the pages after the timeline. Print Your Timeline covers the options.
